Biomechanical evaluation of the modified proximal femoral nail for the treatment of reverse obliquity intertrochanteric fractures.
Sci Rep
January 2025
Department of Orthopedics, Honghui Hospital, Xi'an Jiaotong University, Xi'an, 710054, Shaanxi, China.
The best treatment method for reverse obliquity intertrochanteric fractures (ROIFs) is still under debate. Our team designed the modified proximal femoral nail (MPFN) specially for treating such fractures. The objective of this research was to introduce the MPFN device and compare the biomechanical properties with Proximal Femoral Nail Antirotation (PFNA) and InterTAN nail via finite element modelling.

Non-invasive estimation of pressure differences using 2D synthetic aperture ultrasound imaging offers a precise, low-cost, and risk-free diagnostic tool. Unlike invasive techniques, this preserves natural blood flow and avoids the limitations of devices that occupy lumen space. This paper evaluates a previously published estimator, modified to incorporate Singular Value Decomposition (SVD) echo-cancellation, using data from ten healthy volunteers and one patient.

J Clin Nurs
January 2025
City St George's, University of London, London, UK.
Background: Despite the high acuity of coronary care unit (CCU) patients and their risk of deterioration, little is known about how nurses assess them.
Aim: Increase understanding of the scope of nurses' assessments of deteriorating CCU patients.
Design: Online mixed methods survey.
Fabrication and Performance Enhancement of Wood Liquefaction-Based Carbon Fibers Modified with Alumina Nanoparticles.
Polymers (Basel)
January 2025
College of Resources, Environment and Materials, Guangxi University, Nanning 530004, China.
In this paper, alumina-modified wood liquefaction (AL-WP) was prepared by blending nano-alumina (AlO) into wood liquefaction phenolic resin (WP) using a co-blending method. Alumina-modified wood liquefaction protofilament fiber (AL-WPF) was obtained by melt-spinning, curing, and thermo-curing processes, which were followed by carbonization to obtain alumina-modified wood liquefaction carbon fiber (AL-WCF). This paper focuses on the enhancement effect of nano-alumina doping on the mechanical properties and heat resistance of wood liquefaction carbon fiber (WCF), explores the evolution of graphite microcrystalline structure during the high-temperature carbonization process, and optimizes the curing conditions of AL-WPF.

Materials (Basel)
January 2025
Department of Materials Science and Engineering, National Dong Hwa University, Hualien 974301, Taiwan.
This work proposes dye-sensitized solar cells (DSSCs) with various photoanode designs. A hydrothermal method is used to synthesize hydrangea-shaped TiO (H-TiO) aggregates. The X-ray diffraction (XRD) pattern of H-TiO reveals only an anatase phase.
